antirez c7aaf8db4d Client side caching: implement CLIENT GETREDIR. 
This subcommand may simplify the writing of Redis client libraries
using the tracking feature and/or improve observability and debugging
capabilities.

antirez 463ccf8664 Threaded IO: logging should be safe in I/O threads. 
Potentially it is possible that we get interleaved writes, even if
serverLog() makes sure to write into a buffer and then use printf(), so
even this should be ok. However in general POSIX guarantees that writing
to the same file pointer object from multiple threads is safe. Anyway
currently we *reopen* the file at each call, but for the standard output
logging.

The logging functions actually also access global configuration while
performing the log (for instance in order to check the log level, the
log filename and so forth), however dunring the I/O threads execution
we cannot alter such shared state in any way.

Ubuntu 9bf7f302a7 Threaded IO: stop threads when no longer needed + C11 in Makefile. 
Now threads are stopped even when the connections drop immediately to
zero, not allowing the networking code to detect the condition and stop
the threads. serverCron() will handle that.

antirez f468e653b5 Threaded IO: implement handleClientsWithPendingWritesUsingThreads(). 
This is just an experiment for now, there are a couple of race
conditions, mostly harmless for the performance gain experiment that
this commit represents so far.

The general idea here is to take Redis single threaded and instead
fan-out on expansive kernel calls: write(2) in this case, but the same
concept could be easily implemented for read(2) and protcol parsing.

However just threading writes like in this commit, is enough to evaluate
if the approach is sounding.

Oran Agra acba2fc9b4 slave corrupts replication stream when module blocked client uses large reply (or POSTPONED_ARRAY) 
when redis appends the blocked client reply list to the real client, it didn't
bother to check if it is in fact the master client. so a slave executing that
module command will send replies to the master, causing the master to send the
slave error responses, which will mess up the replication offset
(slave will advance it's replication offset, and the master does not)
